S-91094A120 3/4"-10 Flange Nuts

Key Features & Benefits at a Glance

• Exceptional Load Distribution – The 1 1/2" flange diameter provides a wider bearing surface, reducing surface pressure and preventing damage to connected materials.
• Superior Strength for Demanding Applications – Made from Grade 8 steel, this nut offers high tensile strength and reliability in high-stress environments.
• Vibration-Resistant Fastening – The integrated flange acts as a built-in washer, helping to maintain clamp load and resist loosening under vibration.
• Easy Installation and Removal – The standard external hex profile allows for straightforward application with common wrenches, speeding up assembly.
• Reliable Thread Engagement – 3/4"-10 UNC coarse threads with a Class 2B fit ensure easy starting, quick assembly, and consistent performance.
• Enhanced Durability and Compliance – The steel construction, combined with REACH and RoHS 3 compliance, ensures long-term performance while meeting stringent environmental regulations.
• Optimized Dimensions for Secure Fit – With a flange thickness of 0.16" and a height of 21/32", the nut provides a robust and secure connection.

Professional Applications & Engineering Value

This Grade 8 steel flange nut is engineered to solve critical challenges in heavy machinery, construction, and automotive assembly where vibration and high loads are common. The 1 1/2" flange diameter distributes clamping force over a larger area, preventing surface indentation and material failure in soft or coated substrates. The UNC coarse thread design is ideal for rapid assembly in industrial settings, reducing installation time while the Class 2B thread fit offers a balance between free-running assembly and sufficient engagement strength. Manufactured from high-strength steel, this external hex flange nut maintains its integrity under extreme tension and shear forces, making it a reliable choice for structural frames, equipment mounting, and other heavy-duty applications that demand both performance and regulatory compliance.

Specification Summary & Compliance

This flange nut adheres to standardized dimensions and tolerances, including a UNC thread with Class 2B fit for consistent and reliable performance. It is manufactured to meet the mechanical properties of Grade 8 strength classification. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring it is free from hazardous substances and suitable for use in regulated industrial and international markets.
